We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide …
Based on fertile material collected in January 2019, we report the first record of *Pradosia ptychandra* (Sapotaceae, Chrysophylloideae) to the flora of Amapá state, eastern Brazilian Amazonia. This new record fills a geographical gap between its …
This paper aims to describe and illustrate the fruits, seeds, and seedlings of *Chromolucuma flavilatex* (Chrysophylloideae, Sapotaceae) from central Amazonia and briefly discusses their taxonomic relevance. The observed characters can support our …
In light of the recent findings in Neotropical Chrysophylloideae (Sapotaceae), it can be understood that *Pouteria kossmanniae* is a member of *Lucuma*, not *Pouteria*, which is why we performed a new combination and increased the number of …
Seedling morphology studies have contributed to provide useful data in delimiting different levels of taxonomic groups over the past several decades. Thus, the purpose of this note is to describe on the seedling morphology of *Pouteria franciscana* …
Detailed knowledge about structural attributes and spatial patterns of tree species is fundamental to enable sustainable management of forest resources. However, this knowledge remains poorly understood in the context of eastern Amazonian floodplain …
A new species from central Amazonia, *Chromolucuma brevipedicellata* (Sapotaceae, Chrysophylloideae) is described and illustrated. It occurs in terra firme (non-flooded) forests near Manaus, Brazil. We compare *C. brevipedicellata* to similar species …
Introduction: *Pentaclethra macroloba* is a hyperdominant tree in the Amazon estuary of great socioeconomic importance for the region because the oil from its seeds is a powerful herbal medicine. Objective: We aimed to characterize the morphological …
*Pouteria kossmanniae* (Sapotaceae, Chrysophylloideae), a new species from Central Amazonia, is here described. It is known from the Manaus region, Amazonas, Brazil, and is found in non-flooded upland forests, known as terra firme. Illustrations are …
This is the first record of *Pouteria franciscana* Baehni (Chrysophylloideae, Sapotaceae) in Amapá state, Brazil. We provide a brief description as well as a distribution map, illustrations, and a table with useful features to distinguish *P. …
